AUGUST L. SCHOLLHORN, OF NEW HAVEN, CONNECTICUT, ASSIGNOR TO 1WILLIAM SCHOLLHORN & CO., OF SAME PLACE.

PRUNING IMPLEMENT.

SPECIFICATION forming part of Letters Patent No. 450,342, dated April 14, 1891.

Application filed February 10, 1'91. Serial No. 380,895- (No model.)

To all whom it may concern,.-

Be it known that I, AUGUST L. ScHoLL- HORN, a citizen of the United States, residing at New Haven, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Pruning-Shears; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object to simplify, cheapen, and to generally improve the construction and operation of pruning-shears and other implements of this general class, and at the same time to greatly increase their strength and durability.

With these ends in view I have devised the simple and novel construction of Which the accompanying drawings, is a specification, numerals and letters being used to designate the several parts.

Figure l is a side elevation of the implement complete; Fig. 2, a longitudinal section of the handles, showing one of the blades in elevation, the position of the other blade being indicated by dotted lines; and Fig. 3 is a section on the line o3 a: in Fig. l.

A and A denote the handles, which arev struck up from sheet metal, and HB and B the blades, which are made of suitable shearsteel. The handles are struck up in concavoconvex form, and may of course be given any required outline or configuration. The handles are interchangeable. The pivot end of each handle consists of a pair of ears 2, through which the pivot 3 passes. One of the ears of each handle is provided with an extension 4, to which one of the blades is secured by rivets 5. The blades may of course be given any required shape or configuration.

The manner in which the parts are assembled will be clearly understood in Fig. 3, (which see in connection with Fig. l.) For convenience in description I will designate the ears, which are provided with extensions 4, as 2. (See Fig. 3.) As has already been stated, the two blades are attached to the ears having extensions 4. Outside of these ears, when assembled, are the ears `2, which simply extend to the joint, as clearly shown in Fig. 1. The pivot 3 passes through both pairs of ears and both blades that is, through six independent thicknesses of metal lying in contact with each other, as clearly shown in Fig. 3-so as to give the greatest possible amount of strength at just the point Where strength is required. 'lhis special construction enables me to make implements of this class with ample strength in the handles for any use to which they can possibly be placed, and with greater strength at the pivots than has heretofore been possible, to make the implements much lighter than heretofore, and to make them very much cheaper than has heretofore been possible, using at the same time a fine quality of shear-steel in the blades, it being obvious that it is wholly unnecessary to use anything more than an ordinary grade of metal adapted to be manipulated in dies in forming the "handles,

6 denotes the ordinary spring for throwing the blades to the open position, and 7 a loop attached to one handle, which is adapted to engage a catch 8 upon the other handle, by which the blades may be held in the closed position..

Having thus described my invention, I claim- In pruning implements, a pair of blades and a pair of sheet-metal handles having at their opposite sides ears 2 and 2, the blades being riveted, respectively, to said ears 2, and a pivot passing through both ears 2, both ears 2, and also through both blades, substantially as described,and shown.

In testimony whereof I affix my signature in presence of two witnesses.

AUGUST L. SCHOLLHORN.
